The Heliodor 8 is available with an upper link pin category 2 or 3.
The Heliodor 8 K is available with an upper link pin category 3.
5.2.2 Hollow Discs
The implement consists of two rows of curved and notched hollow discs which are arranged separately on the frame via an intermediate frame. The hollow discs loosen and mix the soil. 5.2.3 Working depth adjustment of hollow discs
The working depth must be adjusted separately for the left and right sides of the implement. This is done using an adjustment mechanism with pins.
5.2.4 Side limitation Side limitation prevents the outer rear right hollow disc and the front left hollow disc from leaving grooves or raising ridges. They are screwed directly onto the frame with their brackets and can be adjusted laterally.
Structure and function
38
5.2.5 Drawbar
The height-adjustable drawbar can be mounted at two heights. This makes it pos-sible among other things to change the intake behaviour and lifting height of the implement. 5.2.6 Levelling tines
The levelling tines lightly level the soil and any existing growth.
5.2.7 Rollers
The rollers ensure reconsolidation and additional crumbling of the soil. During op-eration on the land they bear the weight of the implement if the implement has been lowered for work and they ensure exact depth guiding. The weight of the rollers can also support the feed behaviour of the implement. The implement can be fitted with different roller types.
5.2.8 Hydraulic transportation lock
In the folded in transportation position the hydraulic transportation lock prevents the side parts of the device from unintentionally folding out.
5.2.9 Lighting system
The lighting system contributes significantly to increasing the safety of the imple-ment in road traffic. 5.2.10 Coupling elements
The coupling elements serve to mount the Solitair pneumatic seed drill to the im-plement with an optimum centre of gravity. This ensures that the soil can be culti-vated and the seeds can be sown in the same sequence of operation.
5.2.11 Additional weights
Additional weights can be attached in order to improve the implement's penetra-tion behaviour. This ensures that the implement is also suitable for use in chal-lenging soil conditions.

71
The lower the upper link is mounted on the implement's three-point tower, the greater the pressure load on the rollers – resulting in excellent penetration charac-teristic.
The higher the upper link is mounted on the implement's three-point tower, the lower the pressure load on the rollers – resulting in poor penetration characteris-tic.
If the pressure load is too low and the recompacting or crumbling effect of the rollers is insufficient, the upper link has to be mounted lower on the three-point tower – resulting in excellent penetration characteristic.
If the pressure load is too high and the rollers clogged as a result or if they plunge too far into the soil, the upper link must be mounted higher up on the three-point tower – resulting in poorer penetra-tion characteristic.

11.6 Turning at the headland
DANGER
Risk of damage to components
If the implement is not fully raised, there is a danger that compo-nents may be damaged during an improper turn at the headland.
Before turning at the headland the implement must be completely raised before turning-in to avoid any damage to the implement.
Turning at the headland may only be conducted at a speed suitable for the off-road and ground conditions.
Before turning at the headland
Raise the implement all the way.
After turning at the headland
Lower the implement when driving straight ahead, at a suitable speed, to the preset working depth.
11.7 Working speed
A sufficiently high working speed is required to achieve good work results.
Drive at a working speed of at least 10 km/h so that the soil will be well crumbled and mixed and can be levelled.
Operation
76
11.8 Slotted hole for top link
If the implement is swinging during work or uncontrolled swinging occurs, either a deeper working depth must be chosen or it must be worked with a higher working speed. If this is unsuccessfull, the top link must be connected to the slotted hole (1).
The tractor hydraulic must be set to position control and adjusted so that the top link pin is in the middle of the slotted hole during work.
This prevents a swinging of the implement in all working situations, independently from the working depth and the working speed.
